A review of the weekend's action in the Dutch Eredivisie, including another win for leaders FC Twente.
FC Twente stayed three points clear at the top with a 3-0 win at home to nine-man AZ Alkmaar on Sunday.
Nacer Chadli opened the scoring after 20 minutes and AZ shot themselves in the foot twice in consecutive minutes early in the second half.
The visitors had Adam Maher sent off in the 51st minute and Jozy Altidore dismissed a minute later and after that it was just a question of how many Twente would get.
Dusan Tadic doubled their advantage with a 60th-minute penalty and Luc Castaignos added a third two minutes later.
PSV Eindhoven moved level on points with Vitesse Arnhem in second with a 4-0 win at home to NAC Breda.
Jeremain Lens put PSV in front in the 24th minute and Ola Toivonen got a second on the stroke of half-time.
Mark van Bommel grabbed number three 11 minutes after the break and Georgino Wijnaldum completed the rout five minutes from time.
Champions Ajax slipped up as they were held 1-1 at home to FC Utrecht to fall five points off the early pace.
Ryan Babel put the Amsterdammers ahead in the sixth minute, but Fabian Sporkslede's own goal just five minutes after coming on ensured a share of the spoils.
Bruno Martins Indi scored a 90th-minute leveller to rescue a 2-2 drew for Feyenoord at FC Groningen.
Sekou Cisse put the visitors ahead in the ninth minute, but goals from Leandro Bacuna and Virgil van Dijk had Groningen ahead at the break.
On Saturday, Wilfried Bony claimed a hat-trick but Vitesse missed the chance to take top spot as they were held to a 3-3 draw by visiting Heerenveen.
Bony (53, 70) and Alfred Finnbogason (36, 63) cancelled out each other's efforts but Sven Kums' 74th-minute effort broke the pattern and gave the away side the lead.
Arnold Kruiswijk saw red for Heerenveen just three minutes later and Bony added his third from the penalty spot.
Heracles scored a 3-0 away win over second bottom PEC Zwolle, their second success of the season.
Samuel Armenteros got the ball rolling in the 14th minute before Ninos Gouriye took over with goals in the 68th and 81st minutes.
Roda JC also won 3-0 in their home clash against VVV Venlo.
Sanharib Malki was on target in each half, either side of Mark-Jan Fledderus' 54th-minute effort.
RKC Waalwijk drew 0-0 at Willem II.
On Friday night, ADO Den Haag missed the chance to climb into the top six after being held to a 1-1 draw at NEC Nijmegen.
NEC took the lead two minutes into the second half when Leroy George curled home a free-kick from the edge of the area beyond the grasp of Robert Zwinkels.
ADO secured a share of the spoils in the 58th minute when Mike van Duinen capitalised on an error by Rens Van Eijden to net the equaliser.
